STATUS REPORT ON THE JAMESTOWN OXY-COAL CCS DEMONSTRATION PROJECT

摘要

A fully integrated carbon dioxide capture and storage (CCS) demonstration project based on oxy-coal combustion technology in a Circulating Fluidized Bed (CFB) is being developed for a municipal utility in New York State. This paper will give a status update on the project, which was submitted for funding under the US Department of Energy's Clean Coal Power Initiative. Preliminary results from a FEED study currently underway will be discussed, including cost, design and integration issues. Also reviewed will be the test plan for the demonstration period, which must verify performance and operability issues of importance to utilities considering this technology. The nominal gross output of this combined heat and power facility is projected to be 54 MWe. Scope includes electrical power generation and district heating with near-zero emissions, CO_2 capture, purification and undergroand storage. Advanced technologies for a Flexi-Burn (dual oxidant), circulating fluidized bed boiler (CFB), cryogenic air separation unit (ASU) and CO_2 processing system are to be demonstrated in a commercial operation that will enable direct scale-up to 500 MW size utility power plants. The demonstration plant will replace existing coal fired generation capacity at the Board of Public Utilities' Carlson Station located in southwestern New York State at Jamestown. An alliance of commercial and governmental organizations has been built around the project. Foster Wheeler will supply the CFB as well as combustion expertise. Praxair will provide gas processing technology including the ASU and CO_2 processing unit. The captured CO_2 will be purified and stored in underground saline formations near the site.
